FIELD

The present invention relates to a method and apparatus for reloading aWeb server page in a Web browser, and in particular to a method andapparatus for overcoming the problem of a conflicting reload of a Webserver page in a Web browser.

BACKGROUND

When a Web page is submitted to a server through a hypertext transferprotocol (HTTP) POST request or an HTTP GET request, a Web user thatattempts to refresh the server response may cause the contents of theoriginal request to be resubmitted, possibly causing undesired results,such as a duplicate Web purchase. The reload problem occurs in manysituations. Actions that re-request a document from the server mayinclude: pressing a reload or refresh button; printing or saving theuniform resource locator (URL) in the browser and returning to the pageusing a bookmark or favorite; using back or forward buttons; pressing anenter key in a URL location entry box; and resizing the browser window.Typically, an HTTP response contains a reload request to an URL thatjust displays the result. Accordingly, there exists a need in the art toovercome at least some of the deficiencies and limitations describedherein above.

FIG. 2 illustrates a sequence ID engine 200, in accordance withembodiments of the present invention. Sequence ID engine 200 comprises:sequence ID registers 202A to 202N; corresponding session registers 203Ato 203N; sequence ID test register 204; sequence ID generator 206; and asequence ID comparator 208.

Sequence ID registers 202A to 202N are used for storing a sequence IDafter it the sequence ID is generated.

Session registers 203A to 203N are associated with respective sequenceID registers 202A to 202N and are used for storing the particular usersession associated with a generated sequence ID thereby allowing asequence ID to be associated with a particular user session therebyassociated with all the objects of the associated user session.

Sequence ID test register 204 is used for storing a sequence ID undertest.

Sequence ID generator 206 is used for generating a sequence ID and forsaving the generated sequence ID in sequence ID register 202.

Sequence ID comparator 208 is used for comparing the sequence ID storedin sequence ID register 202 with a sequence ID stored in sequence IDtest register 204.

Sequence ID engine 200 is described in terms of a single sequence ID forsimplicity, however, the embodiments are adapted to handle multiplesequence IDs.

FIG. 3 illustrates an algorithm detailing a request verification method300, in accordance with embodiments of the present invention. Therequest verification method 300 comprises logical process steps 302 to314 for carrying out the steps of an embodiment of the invention.

Step 302 comprises a start of the process.

Step 304 comprises matching a Web service request with Web service bychecking the user session of the Web service.

Step 306 comprises identifying a sequence ID contained in the Webservice request and loading the identified sequence ID into the sequenceID test register 204.

Step 308 comprises checking if the identified sequence ID correspondswith allowable sequence ID for the matched Web service. A look up isperformed using the session registers 203A to 203N to locate associatedsequence registers from sequence ID registers 202A to 202N. Sequence IDcomparator 208 compares the sequence ID in the associated sequenceregister with the sequence ID in sequence ID test register 204. If thesequence IDs corresponds or matches then step 310. If the sequence IDsdo not correspond or match then step 312.

Step 310 comprises allowing the Web request to proceed as it is and theprocess is terminated in step 314.

Step 312 comprises amending the request by stripping out extraparameters from the request and the process is terminated in step 314.

FIG. 4 illustrates an algorithm detailing an example interaction inaccordance with embodiments of the present invention. The algorithm ofFIG. 4 comprises steps 602 to 612 with respect to a single request.

In step 602, a user fills out an order form on a computer client andclicks a submit request. A Web SUBMIT command is sent from the computerclient to a Web service on a server computer.

In step 604, the Web service receives the SUBMIT command and initiates aPOST Command. Nothing is sent back to the client at this stage andnothing is cached.

In step 606, the Web Service checks a sequence ID against an expectedID. If the sequence ID differs from the expected ID, then the parametersin the SUBMIT command are removed. The server sends a confirmation pagecontaining a 2xx success code. If the URL contains the parameters thenstep is 608 is executed. If the parameters are removed then step 612 isexecuted.

In step 608, when the URL contains parameters, the client displays asuccessful order page. If the user refreshes the page then step 610 isexecuted.

In step 610, the user (accidently or intentionally) refreshes the Webpage displaying the order form. However, since the parameters in thesubmit command have been removed then the process recycles from step604.

In step 612, (when the URL does not contain parameters) the clientdisplays a new order form. If the user fills in the form then the userrepeats step 602.

FIG. 5 illustrates an algorithm detailing a further example interactiondiagram, in accordance with embodiments of the present invention. Thealgorithm of FIG. 5 includes an example sequence ID comprising steps 702to 712.

In step 702, a customer requests a page containing possible contextmodification requests such as a purchase. The server generates anexpected sequence ID of 1234.

In step 704, a page is generated with all links or forms containing asequence ID=1234

In step 706, the customer submits a purchase request containing asequence ID=1234. The expected sequence ID is correct and the request isaccepted. The next sequence ID is computed as 1235.

In step 708, a new page is generated with all links or forms containingsequence ID=1235.

In step 710, the customer re-submits the same purchase request withsequence ID=1234. This time the expected sequence ID is incorrect andthe request is rejected. The next sequence ID=1236 is computed.

In step 712, the process is repeated.

FIGS. 6A and 6A, in combination, illustrate an algorithm detailing afurther example interaction diagram, in accordance with embodiments ofthe present invention. The algorithms of FIGS. 6A and 6B comprise steps802 to 824 with particular attention to an application interaction andan example URL.

In step 802, a user requests a page for an online shop. In response, AHTTP GET command (http://server/page) is sent from the client to theserver requesting the page.

In step 804, the server generates a new sequence ID and stores it assession data. The HTTP GET command is forwarded to the application and asecure URL (initSecureUrl http://server/page) is sent back to theserver. A code generator is generated. The code generator is configuredto embed one or more restricted user controls in a Web page associatedwith a sequence ID generator (e.g., sequence ID generator 206 of FIG. 2)internal to sequence ID software engine 200 (of FIG. 2). Any Web requestreceived from a restricted user control includes the sequence IDgenerated by the sequence ID generator. Each sequential request for theWeb service is associated with a next sequential ID in a sequence ofsequence IDs as embedded respectively in the Web page and the Webservice.

In step 806, the server adds the sequence ID to the URL(http://server/page?Id=3452768)

In step 808, the application builds page content including URLs usinggiven prefix such as http://server/page?Id=3452768&Action=Buy. Theapplication responds by sending an HTTP 200 Okay message plus the pagecontent and the server forwards this response to the client.

In step 810, a user clicks on the URL to buy a referenced article. Theclient sends an HTTP GET command including the URL to the server (GEThttp://server/page?Id=3452768&Action=Buy).

In step 812, the server checks that the sequence ID is the expected oneand forwards the command to the application.

In step 814, the application performs the required action and builds aresponse page. An HTTP OK signal is sent back to the server (200 OK+pagecontent).

In step 816, the server generates a new ID and sends it to the client(200 OK plus page content).

In step 818, the user reloads the page by sending an HTTP Get signal tothe server. GET http://server/page?Id=3452768&Action=Buy.

In step 820, the server checks the sequence ID and upon determining thatthe sequence ID is an old sequence ID (by check prior sequence IDs) ordetermining that it is not the same (‘No match’) as the newly generatedID then in step 816, the server removes all elements after the URL (inthis case the elements ‘?Id=3452768&Action=Buy’) and sends the strippeddown URL to the application (GET http://server/page).

In step 822, the server generates a new sequence ID.

In step 824, the application builds response page for stripped down URLrequest and sends an HTTP message signal 200 OK plus the page content tothe server. The server forwards the HTTP message to the client.

Whilst a particular advantage of the preferred embodiment is that thesolution is transparent to the Web service, in a further embodiment itis possible to perform the invention without stripping out the extraparameters of the request and instead passing the request ‘as is’ to theWeb service 102. In this case the application would understand that thesequence ID was not verified and would then ignore the extra elements inthe URL.

Further embodiments of the invention are now described. It will be clearto one of ordinary skill in the art that all or part of the logicalprocess steps of the preferred embodiment may be alternatively embodiedin a logic apparatus, or a plurality of logic apparatus, comprisinglogic elements arranged to perform the logical process steps of themethod and that such logic elements may comprise hardware components,firmware components or a combination thereof.

It will be equally clear to one of skill in the art that all or part ofthe logic components of the preferred embodiment may be alternativelyembodied in logic apparatus comprising logic elements to perform thesteps of the method, and that such logic elements may comprisecomponents such as logic gates in, for example a programmable logicarray or application-specific integrated circuit. Such a logicarrangement may further be embodied in enabling elements for temporarilyor permanently establishing logic structures in such an array or circuitusing, for example, a virtual hardware descriptor language, which may bestored and transmitted using fixed or transmittable carrier media.

In a further alternative embodiment, the present invention may berealized in the form of a computer implemented method of deploying aservice comprising steps of deploying computer program code operable to,when deployed into a computer infrastructure and executed thereon, causethe computer system to perform all the steps of the method.

It will be appreciated that the method and components of the preferredembodiment may alternatively be embodied fully or partially in aparallel computing system comprising two or more processors forexecuting parallel software.
